Hello Experts,

 

I made a intercluster trunk non gatekeeper controlled between call manager clusters.


Created

New Device Pool

New Region

Route Group (Trunk)

Route List

Route pattern.

 

I went to the DNA and here is the output;

OK, but you don;t mention whats the behavior.

You get the "you call cannot be completed..."?

Phone rings but then stops?

Doesn ring?

 

Do you add or remove whatever digits are needed to call the other end?

 

An ICT could be wrong on either side and this affects calls, have you checked the other side??

Correct inbound CSS?

Correct call routing if using prefixes or any other DN transformations?

 

HTH

 

java

 

If this helps, please rate

Thanks Java for your response.

There was no ringing...

Yeah I added digit to call other site.

Yeah configured CSS on both sides (wrong one).

Well I got it working here is some troubleshooting ....

 

Calls from Cluster B Office to Cluster A:

it was giving TCP communication error, strange thing is I had mentioned subscriber IP Address in the remote call manager in ICT configuration page. But Cluster A Call Manager Cluster was not accepting call setup from it. I removed IP Address, saved and put the same IP again. And it started working.

 

CCM traces:

06/06/2010 19:08:13.884 CCM|H225Handler::SdlConnectionInd, rejecting the TCP connection from IP=10.112.211.201. Incoming H225 call on Port=1720, can find this port in the registered H323 endpoints port list.

 

Calls from Cluster A to Cluster B:

The IP Phone(test Phone) partition was not included in the CSS that I specified in the trunk config.

 

06/06/2010 20:29:22.086 CCM|Digit analysis: wait_DmPidErr - Name=Unregistered Pid=(0,0,0)

06/06/2010 20:29:22.086 CCM|Digit analysis: wait_DmPidErr: dialingPartition=[410129cb-cb8b-7e5c-86d1-beb774c36c46] dialingPattern=[6919] dialingWhere=[], PID=(0,0,0)

 

Cluster Bs route plan report showed 2 entries for 6919, one in Part_EM the other in Part_Internal.  The original digit analysis showed the following:

 

06/06/2010 20:29:22.085 CCM|Digit analysis: match(pi="2", fqcn="", cn="6001",plv="5", pss="Part_EM:Part_Internal:VMPilotNumberPT:VMRestrictedPT:Part_National:Part_Mobile:Part_Local:Part_TollFree:Part_Emergency:Part_E1_EM:Part_E1_Emergency:Part_PMT_Local:Part_E1_Mobile:Part_E1_National:Part_E1_Toll_Free_calls:Part_International:Part_E1_International:Part_E1_Tollfree2:huntpilot_partition:Part_STC_Helpline:Part_TollFree2:Airline_Part", TodFilteredPss="Part_EM:Part_Internal:VMPilotNumberPT:VMRestrictedPT:Part_National:Part_Mobile:Part_Local:Part_TollFree:Part_Emergency:Part_E1_EM:Part_E1_Emergency:Part_PMT_Local:Part_E1_Mobile:Part_E1_National:Part_E1_Toll_Free_calls:Part_International:Part_E1_International:Part_E1_Tollfree2:Part_STC_Helpline:Part_TollFree2:Airline_Part", dd="6919",dac="0")

 

Note that after "pss=" Part_EM is first in the list thus CUCM tried to route the call to EM device profile not the actual phone.  I removed this partition from CSS used by ICT, we retested and the call  6001 to 6919 completed properly.

 

I will put a complete document for ICT so other dont get stuck as I got

 

 

Thanks & Regards,

Hi.

I see you got this working, but I think the error (rejecting the TCP  connection from IP=10.112.211.201. Incoming H225 call on Port=1720,  can find this port in the registered H323 endpoints port list) really points directly to misconfigured Device Pool/CCM Group.

 

Check out the SRND:

"It is important to configure a corresponding intercluster trunk (non-gatekeeper controlled) that has a Unified CM Group containing the same servers that were defined as remote Unified CM servers in the first cluster. A similar configuration is required in each Unified CM cluster connected by the intercluster trunks."

 

Cheers,

 

Tore
